HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Short-Term Municipal Bond Fund I
share class posted a total return of 2.93%. (For information on other share
classes and performance comparisons to indexes, please see page 3.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
The major events influencing the municipal bond market over the past fiscal year
were much the same as those influencing the taxable bond market. In an effort to
slow down the U.S. economy and ward off inflationary pressures, the Federal
Reserve took on a restrictive posture. As rates moved up, bond markets weakened.
Furthermore, the specter of Y2K and a year of dropping bond prices led to a
highly illiquid market in the final months of 1999.

At the start of the new year a relief rally surfaced, lasting for almost the
entire first quarter of 2000. Municipal bond prices firmed as the market easily
digested a light supply of new issues. But, in mid-April, a still-growing
economy generated a sell-off in the market, which stifled the first quarter's
price gains.

At the end of May, we saw a very resilient market turn on a dime as dealers
looked to fill the anticipated strong retail demand coming in June and
July--typically the biggest months for coupon payment, bond calls and bond
maturities. This rally led to yield declines across the curve.

HOW DID THESE EVENTS AFFECT THE FUND'S YIELD?
The Fund's yield increased during the year, due to the rising interest rate
environment and our active management strategies. As of June 30, 2000, the
Fund's 30 day SEC yield on I shares was 4.64%, compared to 3.80% on June 30,
1999. (For investors in the 39.6% federal income tax bracket, the 4.64%
tax-exempt yield translates to a taxable-equivalent yield of 7.68%.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
To offset the effects of the Federal Reserve's interest rate policy, we began
aggressively shortening the Fund's average duration during the first quarter of
calendar year 2000. (Duration is a measure of a fund's sensitivity to interest
rate changes. A longer duration indicates greater sensitivity; a shorter
duration indicates less.) To maintain an attractive yield in the Fund, we used
LIBOR-based floating-rate securities, which offered a higher yield than other
types of floating-rate securities. Then, at the end of the first quarter of
calendar year 2000, we began extending the Fund's duration. This enhanced Fund
performance, as municipal bond prices recovered strongly through June 2000.

An anomaly occurred around tax time. As investors typically redeem shares to
meet their tax payments, dealers usually pump up short-term municipal rates to
help keep inventories low. When investors did not come back into the market,
dealers were forced to keep short-term rates artificially high for a protracted
period. This enabled the Fund to earn higher-than-normal returns with
shorter-than-normal duration. As rates began their reversion to the norm, we
were able to purchase attractively priced bonds that enhanced yield and total
return. With the rally that began in late May, these bonds appreciated in price.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
On June 30, 2000, 31% of the Fund was invested in "AAA"-rated securities, 8% in
"AA," 11% in "A," 14% in "BBB," and 36% in other and non-rated securities.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's action over the past year has led us to hold a
higher-than-normal cash balance and a shorter-than-normal average duration in
the Fund. With signs of a slowing economy, we believe the Federal Reserve may be
near the end of its tightening campaign. As such, we plan to continue our
efforts to move the Fund's duration closer to an average position.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The above-quoted performance data includes the performance of the Pegasus Short
Municipal Bond Fund prior to the acquisition by the One Group Short-Term
Municipal Bond Fund on March 22, 1999.

The performance of the Short-Term Municipal Bond Fund is measured against the
Lehman Brothers 3 Year Municipal Bond Index, an unmanaged index generally
representative of the short-term municipal bond market. Investors are unable to
purchase the index directly, although they can invest in the underlying
securities. The performance of the index does not reflect the deduction of
expenses associated with a mutual fund, such as investment management fees. By
contrast, the performance of the Fund reflects the deduction of these services
as well as the deduction of sales charges on Class A shares and applicable
contingent deferred sales charges on Class B shares.

The Lipper Short-Term Municipal Debt Fund Index consists of funds that invest in
municipal debt issues with dollar-weighted average maturities of one to three
years.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Intermediate Tax-Free Bond Fund I
share class posted a total return of 2.19%. (For information on other share
classes and performance comparisons to indexes, please see page 5.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
The major events influencing the municipal bond market over the past fiscal year
were much the same as those influencing the taxable bond market. In an effort to
slow down the U.S. economy and ward off inflationary pressures, the Federal
Reserve took on a restrictive posture. As rates moved up, bond markets weakened.
Furthermore, the specter of Y2K and a year of dropping bond prices led to a
highly illiquid market in the final months of 1999.

At the start of the new year a relief rally surfaced, lasting for almost the
entire first quarter of 2000. Municipal bond prices firmed as the market easily
digested a light supply of new issues. But, in mid-April, a still-growing
economy generated a sell-off in the market, which stifled the first quarter's
price gains.

At the end of May, we saw a very resilient market turn on a dime as dealers
looked to fill the anticipated strong retail demand coming in June and
July--typically the biggest months for coupon payment, bond calls and bond
maturities. This rally led to yield declines across the curve.

HOW DID THESE EVENTS AFFECT THE FUND'S YIELD?
As interest rates generally increased during the year, so did the Fund's yield.
As of June 30, 2000, the Fund's 30 day SEC yield on I shares was 4.71%, compared
to 4.45% on June 30, 1999. (For investors in the 39.6% federal income tax
bracket, the 4.71% tax-exempt yield translates to a taxable-equivalent yield of
7.80%.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Going into the end of 1999, we attempted to keep the Fund very liquid. This
strategy worked well, given the illiquid nature of the municipal market during
the final few months of 1999. The market's illiquidity contributed to a period
of heavy redemptions during November and December 1999. Redemptions continued
through tax season, as investors withdrew funds to meet their 1999 tax bills.
This redemption activity led us to sell bonds in an attempt to keep the Fund's
cash position at a comfortable level. Because of this, the Fund was unable to
benefit from the relief rally that emerged in the first quarter of 2000.

Nevertheless, the Fund has participated in the latest rally that began in late
May. With more supply moving into the market, we decided to extend the Fund's
duration by purchasing high-quality, highly-liquid bonds. (Duration is a measure
of a fund's sensitivity to interest rate changes. A longer duration indicates
greater sensitivity; a shorter duration indicates less.) As interest rates
started declining in late May, the Fund's price performance benefited from the
portfolio's longer duration.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's overall credit quality remained solid during the year. On June 30,
2000, 48% of the Fund was invested in "AAA"-rated securities, 28% in "AA," 9% in
"A," 5% in "BBB," and 10% in other and non-rated securities.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's action over the past year has led us to hold a
higher-than-normal cash balance and a shorter-than-normal average duration in
the Fund. With signs of a slowing economy, we believe the Federal Reserve may be
near the end of its tightening campaign. As such, we plan to continue our
efforts to move the Fund's duration closer to its average of 5.9 years.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The performance of the Intermediate Tax-Free Bond Fund is measured against the
Lehman Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of
investment grade municipal bonds with maturities close to seven years. Investors
are unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lipper Intermediate Municipal Fund Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Tax-Free Bond Fund I share class
posted a total return of 2.64%. (For information on other share classes and
performance comparisons to indexes, please see page 8.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MUNICIPAL MARKET?
Overall, interest rates moved higher during the 12-month period ending June 30,
2000. In general, municipal bond rates followed the moves of the Treasury
market, which reacted to changing expectations regarding Federal Reserve policy.
When economic indicators showed strong economic growth and signs of inflation,
expectations that the Federal Reserve would raise rates pushed bond prices
lower. But, after economic reports late in the fiscal year indicated a slowdown
in economic growth, expectations for further rate hikes over the near term
diminished, and the bond market rallied.

Strong stock market performance in the fourth quarter of 1999 affected the bond
markets, as investors continued to flock to stocks at the expense of bonds. This
forced most municipal bond mutual funds to sell securities in order to meet
redemptions. Because the supply created from mutual fund selling far outpaced
demand, the market weakened. The Fund experienced heavy redemptions during this
period, but its large cash position enabled us to meet redemptions without being
forced to sell bonds into the illiquid market.

The concentration of wealth in California led to strong demand for California
municipal bonds. This heavy demand drove California municipal bond prices
significantly higher than municipal bond prices in other states. We were able to
take advantage of this demand by selling some of the Fund's California bonds at
very high levels and purchasing more attractively priced bonds issued by other
states.

HOW DID THE FUND'S YIELD CHANGE?
Providing a high level of tax-exempt income is one of the Fund's primary goals.
The Fund's yield increased during the year as a result of portfolio management
strategies as well as rising interest rates. As of June 30, 2000, the Fund's 30
day SEC yield on I shares was 4.93%, compared to 4.49% on June 30, 1999. (For
investors in the 39.6% federal income tax bracket, the 4.93% tax-exempt yield
translates to a taxable-equivalent yield of 8.16%.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our investment strategy during the first half of the fiscal year was to maintain
a shorter-than-market duration and a large cash balance in anticipation of a
weak market with poor liquidity. This strategy proved effective, as municipal
bond prices declined during that period. In the second half of the fiscal year,
our primary strategy was to increase the Fund's yield and to restructure and
extend the Fund's average maturity. As such, we moved the Fund's duration to a
more neutral stance of approximately 7.5 years. (Duration is a measure of a
fund's sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) This effort was effective
because the market improved, and the lengthening of duration allowed the Fund to
participate in the declining rate environment.

In the first half of the fiscal year, housing bonds were strong performers due
to the rising interest rate environment. The Fund's exposure to this sector
positively contributed to performance. In the second half zero-coupon bonds and
intermediate- to long-duration bonds with call protection were the best
performers in the Fund. (The "call" feature refers to the bond issuer's right to
repay, or "call," the bond before the scheduled maturity date. Securities that
have call protection are protected from this.)

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's overall credit quality remained high, with more than 54% of the
Fund's assets invested in "AAA"-rated securities. Securities rated "AA"
comprised 35% of Fund assets; "A"-rated, 8%; and "BBB"-rated, 2%. We take
advantage of opportunities to enhance the Fund's yield by purchasing bonds rated
below "AAA" when the yield advantages compensate for the lower credit rating.

WHAT IS YOUR OUTLOOK FOR THE FUND?
Our goals are to continue striving for an attractive total return and generating
a relatively strong SEC yield. To realize those goals, we will continue to take
advantage of yield curve opportunities and to invest in what we believe are the
most attractive credits and sectors.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The above-quoted performance data includes the performance of the Pegasus
Municipal Bond Fund prior to the acquisition by the One Group Tax-Free Bond Fund
on March 22, 1999. Prior to February 1, 1995, performance for the Class I shares
is based on Class A share performance adjusted to reflect the absence of sales
charges.

The performance of the Tax-Free Bond Fund is measured against the Lehman
Brothers Municipal Bond Index, an unmanaged index generally representative of
the municipal bond market as a whole. Investors are unable to purchase the index
directly, although they can invest in the underlying securities. The performance
of the index does not reflect the deduction of expenses associated with a mutual
fund, such as investment management fees. By contrast, the performance of the
Fund reflects the deduction of these services as well as the deduction of sales
charges on Class A shares and applicable contingent deferred sales charges on
Class B shares.

The Lipper General Municipal Debt Fund Index consists of funds that invest at
least 65% of its assets in municipal debt issues in the top four credit ratings.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Municipal Income Fund I share class
posted a total return of 0.32%. (For information on other share classes and
performance comparisons to indexes, please see pages 10-11.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
The major events influencing the municipal bond market over the past fiscal year
were much the same as those influencing the taxable bond market. In an effort to
slow down the U.S. economy and ward off inflationary pressures, the Federal
Reserve took on a restrictive posture. As rates moved up, bond markets weakened.
The specter of Y2K and a year of dropping bond prices led to a highly illiquid
market in the final months of 1999.

A relief rally surfaced after the new year and lasted for almost the entire
first quarter of 2000. Municipal bond prices firmed as the market easily
digested a light new-issue supply. But, the sell-off in the market in mid-April,
brought on by a still-growing economy, stifled any price gains realized in the
first quarter.

At the end of May, we saw a very resilient market turn on a dime as dealers
looked to fill the anticipated strong retail demand of June and July--typically
the biggest months for coupon payment, bond calls and bond maturities. This
rally led to yield declines across the curve.

HOW DID THESE EVENTS AFFECT THE FUND'S YIELD?
With interest rates generally on an upward course during the year, the Fund's
yield increased. As of June 30, 2000, the Fund's 30 day SEC yield on I shares
was 5.22%, compared to 4.97% on June 30, 1999. (For investors in the 39.6%
federal income tax bracket, the 5.22% tax-exempt yield translates to a
taxable-equivalent yield of 8.64%.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
To keep the yield on the Fund attractive, we invested in intermediate- and
longer-maturity multi-family housing revenue bonds. At the time, these bonds
represented the best value in the market. But, when the Federal Reserve began
raising rates, we were a bit slow in selling off these bonds. As a result, the
Fund suffered losses from rising interest rates and a widening of the bid/ask
spread on the types of bonds the Fund was heavily invested in. We continue to
buy bonds in the housing sector, but we prefer to focus on shorter-duration,
higher-coupon housing bonds that have been the hallmark of the Fund since its
inception.

The Fund experienced net redemptions from late October through late April. This
made duration management more challenging than usual. (Duration is a measure of
a fund's sensitivity to interest rate changes. A longer duration indicates
greater sensitivity; a shorter duration indicates less.) With an illiquid market
in the last quarter of 1999 and the first quarter of 2000, we decided to
maintain a lower-than-normal duration by holding a higher-than-normal cash
balance. This strategy led to more stable price performance throughout the
volatile first half of 2000. In late May, as the market rallied from renewed
retail investor demand, we started extending duration using high-quality bonds.
This strategy enhanced performance during the fiscal year's final quarter. The
Fund ended the fiscal year with a duration of 6.0 years, compared to 6.7 years
on June 30, 1999.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's overall credit quality remained solid during the year. On June 30,
2000, 39% of the Fund was invested in "AAA"-rated securities, 25% in "AA," 19%
in "A," 6% in "BBB," and 12% in other and non-rated securities.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's action over the past year has led us to hold a
higher-than-normal cash balance and a shorter-than-normal average duration in
the Fund. With signs of a slowing economy, we believe the Federal Reserve may be
near the end of its tightening campaign. As such, we plan to continue our
efforts to move the Fund's duration closer to its average of 5.7 years through
the addition of high-quality, well-structured bonds. As always, we plan to focus
on municipal housing bonds, as they exhibit the defensive characteristics that
are the cornerstone of the Fund.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The performance of the Municipal Income Fund is measured against the Lehman
Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of investment
grade municipal bonds with maturities close to seven years. Investors are unable
to purchase the index directly, although they can invest in the underlying
securities. The performance of the index does not reflect the deduction of
expenses associated with a mutual fund, such as investment management fees. By
contrast, the performance of the Fund reflects the deduction of these services
as well as the deduction of sales charges on Class A shares and applicable
contingent deferred sales charges on Class B and Class C shares.

The Lipper Intermediate Municipal Fund Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Arizona Municipal Bond Fund I share
class posted a total return of 2.66%. (For information on other share classes
and performance comparisons to indexes, please see page 14.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
Overall, the municipal market was influenced negatively by the continuing
strength of the U.S. economy and the Federal Reserve's edict to be in front of
the inflation curve. The Federal Reserve increased the federal funds rate five
times in the past 12 months, pushing the federal funds rate 1.75 percentage
points higher to 6.50%. A positive factor for the government bond market was the
U.S. Treasury's buyback program of outstanding long-term bonds. This helped
create an inverted government yield curve, which reflects short-term rates that
are higher than long-term rates. The reduction of outstanding Treasury debt
effectively eliminated a measure of valuing municipals by comparing municipal
yields as a percentage of Treasury yields.

While the 30-year Treasury showed strength, all other markets, including the
municipal market, struggled. In addition, the municipal market had to absorb a
changing of the guard. In recent years, mutual funds and insurance companies
were the major buyers of municipal bonds. The historically flat municipal yield
curve substantially hurt the competitiveness of municipal funds versus
individual bonds. Furthermore, individual investors continued to favor the stock
market over all areas of the bond market.

In Arizona, the significant event was the continuing decline in bond issuance.
For calendar year 1999, new issuances of Arizona bonds declined 21% to $3.3
billion from $4.2 billion in 1998. Current projections for calendar 2000 are for
an issuance of $1.8 billion, a decline of 45% from 1999 levels and less than
half of the 1998 issuance. As projected, following passage of the Students First
legislation in 1998, school district financing is leading the drop. For the
first six months of 2000, issuance of school district bonds was approximately
$75 million. This compares to $448 million for all of 1999 and $627 million for
1998. To date, tepid demand has offset the decline in supply, but if demand for
income-oriented products increases, Arizona bonds could become difficult to
locate. At the end of June, 10-year insured Arizona bonds were yielding 5.10%,
and long-term yields were near 5.85%.

HOW DID THE FUND'S YIELD CHANGE?
The rising interest rate environment throughout most of the period helped push
the Fund's yield higher, from 3.99% on June 30, 1999, to 4.63% on June 30, 2000.
(For investors in the 39.6% federal income tax bracket and 5.2% Arizona state
bracket, the 4.63% tax-exempt yield translates into an 8.07% taxable-equivalent
yield.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
We concentrated our trading activity on maintaining cash reserves to meet
liquidity needs. We also focused on lowering the Fund's duration from 6.7 years
on June 30, 1999, to a target average of 6 years. (Duration is a measure of a
fund's sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) The decline in duration helped
limit the Fund's volatility, but in hindsight, we would have achieved better
results with an even shorter duration target.

Throughout the year we maintained an emphasis on quality issues. More than 90%
of the Fund generally was invested in "AAA"-rated insured or "AA"-rated bonds.
Likewise, sector distributions did not change dramatically, with 40% of the
portfolio invested in general obligation bonds and 60% in revenue-specific
bonds. Moreover, we limited the Fund's participation in the health care sector
to hospital issues offering the added credit-quality enhancement of insurance.*

WHAT IS YOUR OUTLOOK FOR THE FUND?
Going forward, we remain cautiously optimistic on the market. Our caution stems
from a still-growing economy and possible inflationary pressures ahead. Our
optimism is based on the same growing economy, but one growing at a much slower
pace as the effect of higher interest rates takes hold.

As always, our goal is to increase the Fund's income with minimum risk to the
Fund's net asset value. We

view the decline in Arizona bond issuance as helping and hindering this
endeavor. A decline in supply should increase value and improve the Fund's net
asset value. But, lower supply means a smaller selection of bonds as we attempt
to maintain and improve our income flow. Our strategy is to maintain the Fund's
intermediate maturity structure, continue purchasing quality credits, and
improve coupon and call protection of the Fund's holdings. We believe the Fund's
current duration is reasonable, but moving it slightly higher would improve
relative performance should interest rates level off or start to decline.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The above-quoted performance data includes the performance of a collective trust
fund for the period prior to the commencement of operations of the mutual fund
on January 20, 1997, adjusted to reflect the expenses associated with the Fund.
The collective trust fund was not registered under the Investment Company Act of
1940 ("1940 Act") and, therefore, was not subject to certain investment
restrictions, limitations and diversification requirements imposed by the 1940
Act and the Internal Revenue Code. If the collective trust fund had been
registered under the 1940 Act, its performance may have been adversely affected.

The performance of the Arizona Municipal Bond Fund is measured against the
Lehman Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of
investment grade municipal bonds with maturities close to seven years. Investors
are unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lipper Intermediate Municipal Fund Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Kentucky Municipal Bond Fund I share
class posted a total return of 2.83%. (For information on other share classes
and performance comparisons to indexes, please see page 17.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
As expected, the municipal market took its cue from the Treasury market, and
ultimately the Federal Reserve. As such, the market came under price pressure
for most of the fiscal year, as interest rates generally moved upward. The
negative impact of the Federal Reserve's interest rate hikes was more than
enough to offset a number of positive factors that surfaced during the year. In
1998 the market experienced the second-highest year on record for new issuance.
But since then, the volume of new issuance has declined steadily to its current
pace that is 40% below that of 1998. In addition, the strong economy has helped
foster improvements in municipal credit ratings, with ratings upgrades outpacing
downgrades by a seven-to-one margin.

Nevertheless, these positive factors were not enough to prevent the municipal
market from underperforming the Treasury market. Declining supply, due to the
government surplus and the U.S. Treasury's buyback program of long-term debt,
and the occasional "flight to quality" caused Treasuries to outperform municipal
securities as well as agency and corporate bonds. We believe this pattern is not
likely to change any time soon, as the expected future surpluses should mean
more pay-down of debt.

HOW DID THE STATE'S ECONOMY FARE?
Kentucky registered another year of growth in 1999, as gains in the
transportation equipment and service sectors more than offset declines in the
state's more traditional industries, such as apparel, coal and tobacco. This
shift in production has been going on for the past decade and represents a
continuation of the strengthening of the larger metropolitan areas while the
small, rural segments struggle. The state's employment growth remained at the
same pace as the past few years, with the overall unemployment rate hovering
around the national average at 4.3%.

The adoption of strong budgetary practices earlier in the decade has helped
produce a balanced budget on a regular basis, with a stabilization fund equal to
4% of general fund revenues. The state is taking steps to increase this fund to
5%.

The near-term outlook points to a continuation in the trend of positive growth.
The areas of concern remain slow population growth and the weakening of the
state's traditional industries. The state's central geographic location and the
steps to diversify the economic base have helped and should continue to help
overcome these negatives.

HOW DID MARKET EVENTS INFLUENCE PERFORMANCE?
The general increase in interest rates caused the Fund's share price to decline
over the 12-month period. The major contributor to performance was the Fund's
relatively high level of income, which offset the price depreciation and kept
the Fund's total return positive.

In response to the jump in tax-free interest rates over the fiscal year, the
Fund's 30 day SEC yield on I shares increased from 4.18% on June 30, 1999, to
4.61% on June 30, 2000. (For investors in the 39.6% federal income tax bracket
and the 6.0% Kentucky state bracket, the 4.61% tax-exempt yield translates into
an 8.12% taxable-equivalent yield.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Our primary investment strategy continues to involve purchasing high-quality,
full-coupon, intermediate-maturity bonds exhibiting good call structures within
all sectors of the Kentucky market. (Call refers to a bond issuer's right to
repay, or "call," the bond prior to its maturity date.) This strategy is
designed to provide a good income stream while offering price protection when
interest rates rise.

Our strategy was put to the test during the past fiscal year, as the goal of
maintaining a high, steady stream of income conflicted with the goal of
maximizing total return. As interest rates increased, we initiated sales and
swaps to raise cash and shorten the Fund's duration. (Duration is a measure of a
fund's sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) These efforts were offset
partially by Fund redemp-

tions (primarily as investors moved into equities or withdrew their assets to
meet tax obligations) and the upward migration of interest rates. Nevertheless,
the Fund's duration did decline enough--from 5.6 years on June 30, 1999, to 5.0
years on June 30, 2000--to help foster a relatively attractive total return
while maintaining a good income stream.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's average credit quality remained high during the fiscal year, with 84%
of the Fund invested in securities rated "AA" or better on June 30, 2000,
compared to 74% on June 30, 1999. This increase was due primarily to the Fund's
position in school building revenue bonds, which were upgraded from an "A"
rating to rating of "AA."

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's string of tightening moves over the past year finally
appears to be having the desired impact of slowing the economy. But, the current
expansion has displayed a remarkable level of resiliency. The chance of the
economy heating up again, coupled with the recent pick-up in the pace of
inflation, suggests that the Federal Reserve's job may not be over yet. This
translates into a market that may remain volatile and experience considerable
swings in sentiment over the near term. Our strategy in this environment will
continue to involve keeping a higher level of cash and controlling duration via
outright sales and swaps.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original

The above-quoted performance data includes the performance of the Trademark
Kentucky Municipal Bond Fund prior to the acquisition by the One Group Kentucky
Municipal Bond Fund on January 20, 1995. Prior to January 20, 1995, performance
for Class A shares is based on Class I share performance adjusted to reflect the
expenses and sales charges applicable to Class A shares.

The performance of the Kentucky Municipal Bond Fund is measured against the
Lehman Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of
investment grade municipal bonds with maturities close to seven years. Investors
are unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lipper Intermediate Municipal Fund Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Louisiana Municipal Bond Fund I
share class posted a total return of 2.81%. (For information on other share
classes and performance comparisons to indexes, please see page 20.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
As expected, the municipal market took its cue from the Treasury market, and
ultimately the Federal Reserve. As such, the market came under price pressure
for most of the fiscal year, as interest rates generally moved upward. The
negative impact of the Federal Reserve's interest rate hikes was more than
enough to offset a number of positive factors that surfaced during the year. In
1998 the market experienced the second-highest year on record for new issuance.
But since then, the volume of new issuance has declined steadily to its current
pace that is 40% below that of 1998. In addition, the strong economy has helped
foster improvements in municipal credit ratings, with ratings upgrades outpacing
downgrades by a seven-to-one margin.

Nevertheless, these positive factors were not enough to prevent the municipal
market from underperforming the Treasury market. Declining supply, due to the
government surplus and the U.S. Treasury's buyback program of long-term debt,
and the occasional "flight to quality" caused Treasuries to outperform municipal
securities as well as agency and corporate bonds. We believe this pattern is not
likely to change any time soon, as the expected future surpluses should mean
more pay-down of debt.

HOW DID THE STATE'S ECONOMY FARE?
Louisiana continued to make slow, steady progress on the financial front. The
strength in the national economy, improvements in the state's financial process
and steps to diversify the overall economic base have had a positive influence
on the state's economic growth.

Nevertheless, these initiatives are being offset by the continued presence of
lingering problems. Notwithstanding the efforts to diversify the state's
economic base, the cyclical energy sector continues to dominate. In addition,
the state budgetary process has been redirected to better match revenues and
expenditures, with any surpluses used to pay down outstanding debt. As expected,
this has limited the amount of investment the state has made to compete in the
future.

The near-term outlook for Louisiana suggests a continuation of the slow, steady
pace of growth that has been experienced over the past few years. Debt levels
are being reduced and diversification is taking place, but the reliance on the
volatile energy sector will make progress uneven for the time being.

HOW DID MARKET EVENTS INFLUENCE PERFORMANCE?
The general increase in interest rates caused the Fund's share price to decline
over the 12-month period. The major contributor to performance was the Fund's
relatively high level of income, which offset the price depreciation and kept
the Fund's total return positive.

In response to the jump in tax-free interest rates over the fiscal year, the
Fund's 30 day SEC yield on I shares increased from 4.24% on June 30, 1999, to
4.69% on June 30, 2000. (For investors in the 39.6% federal income tax bracket
and the 6.0% Louisiana state bracket, the 4.69% tax-exempt yield translates into
an 8.27% taxable-equivalent yield.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Because our investment selections are limited to the state of Louisiana, we
consider bonds in all market sectors. Our primary investment strategy continues
to involve purchasing high-quality, full-coupon, intermediate-maturity bonds
with good call structures. (Call refers to a bond issuer's right to repay, or
"call," the bond prior to its maturity date.) This strategy is designed to
provide a good income stream while offering price protection when interest rates
rise.

This past fiscal year demonstrated that trying to generate a high, steady stream
of income while maintaining a stable net asset value can be challenging dual
goals. As interest rates increased, we initiated sales and swaps to raise cash
and shorten the Fund's duration, which moved from 6.2 years on June 30, 1999, to
5.5 years on June 30, 2000. (Duration is a measure of a fund's sensitivity to
interest rate changes. A longer duration indicates greater sensitivity; a
shorter duration indicates less.) But these efforts were largely offset by Fund
redemptions (primarily as investors moved into

equities or withdrew their assets to meet tax obligations) and the upward
migration of interest rates, which pushed duration to more than 6 years during
the third and fourth quarters of 1999. When all was said and done, the Fund's
duration did decline sufficiently to keep total return relatively attractive and
provide a good income stream.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's average credit quality remained high during the fiscal year, with 82%
of the Fund invested in securities rated "AA" or better on June 30, 2000,
slightly lower than 83% on June 30, 1999.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's string of tightening moves over the past year finally
appears to be having the desired impact of slowing the economy. But, the current
expansion has displayed a remarkable level of resiliency. The chance of the
economy heating up again, coupled with the recent pick-up in the pace of
inflation, suggests that the Federal Reserve's job may not be over yet. This
translates into a market that may remain volatile and experience considerable
swings in sentiment over the near term. Our strategy in this environment will
continue to involve keeping a higher level of cash and controlling duration via
outright sales and swaps.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The above-quoted performance data includes the performance of the Paragon
Louisiana Tax-Free Fund for the period before it was acquired by the One Group
Louisiana Municipal Bond Fund on March 26, 1996. Prior to March 26, 1996,
performance for the Class I shares is based on Class A share performance
adjusted to reflect the absence of sales charges.

The performance of the Louisiana Municipal Bond Fund is measured against the
Lehman Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of
investment grade municipal bonds with maturities close to seven years. Investors
are unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lipper Intermediate Municipal Fund Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Michigan Municipal Bond Fund I share
class posted a total return of 1.28%. (For information on other share classes
and performance comparisons to indexes, please see page 23.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
As expected, the municipal market took its cue from the Treasury market, and
ultimately the Federal Reserve. As such, the market came under price pressure
for most of the fiscal year, as interest rates generally moved upward. The
negative impact of the Federal Reserve's interest rate hikes was more than
enough to offset a number of positive factors that surfaced during the year. In
1998 the market experienced the second-highest year on record for new issuance.
But since then, the volume of new issuance has declined steadily to its current
pace that is 40% below that of 1998. In addition, the strong economy has helped
foster improvements in municipal credit ratings, with ratings upgrades outpacing
downgrades by a seven-to-one margin.

Nevertheless, these positive factors were not enough to prevent the municipal
market from underperforming the Treasury market. Declining supply, due to the
government surplus and the U.S. Treasury's buyback program of long-term debt,
and the occasional "flight to quality" caused Treasuries to outperform municipal
securities as well as agency and corporate bonds. We believe this pattern is not
likely to change any time soon, as the expected future surpluses should mean
more pay-down of debt.

HOW DID THE STATE'S ECONOMY FARE?
The Michigan economy, the nation's eighth largest, remained strong during the
fiscal year. The budgetary restraint measures enacted to address imbalances in
the early 1990s, coupled with the large manufacturing presence, have helped the
state post a string of budget surpluses and replenish reserves that were
depleted during the prior downturn. This growth further aided in the increase in
the state's stabilization fund to 6.6% of general fund expenditures--nearly 50%
higher than just five years ago.

A further indication of the strength of the state's economy is the fact that
employment growth has been outstripping the national average. This has led to
the lowest unemployment rate in a decade and, at 3.7%, one of the lowest in the
nation.

The near-term outlook points to a continuation of solid economic growth. The
large manufacturing presence (25% of the state economic base) does inject a
level of volatility. But, a number of measures to invest in both technology and
education along with steps to diversify the state's economic base should help
Michigan reduce and withstand the impact of any future downturn in
manufacturing.

HOW DID MARKET EVENTS INFLUENCE PERFORMANCE?
The general increase in interest rates caused the Fund's share price to decline
over the 12-month period. The major contributor to performance was the Fund's
relatively high level of income, which offset the price depreciation and kept
the Fund's total return positive.

In response to the jump in tax-free interest rates over the fiscal year, the
Fund's 30 day SEC yield on I shares increased from 4.52% on June 30, 1999, to
4.86% on June 30, 2000. (For investors in the 39.6% federal income tax bracket
and the 4.3% Michigan state bracket, the 4.86% tax-exempt yield translates into
an 8.44% taxable-equivalent yield.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
With our investment selections limited to municipal bonds issued in the state of
Michigan, we evaluate securities in all market sectors. Our primary investment
strategy continues to involve purchasing high-quality, full-coupon,
intermediate-maturity bonds with good call structures. (Call refers to a bond
issuer's right to repay, or "call," the bond prior to its maturity date.) This
strategy is designed to provide a good income stream while offering price
protection when interest rates rise.

This past fiscal year put our ongoing strategy to test, as the market
environment made it difficult to maintain a high stream of income and maximize
total return at the same time. With interest rates on the upswing, we initiated
sales and swaps to raise cash and shorten the Fund's duration, which moved from
7.7 years on

June 30, 1999, to 7.0 years on June 30, 2000. (Duration is a measure of a fund's
sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) But these efforts were largely
offset by Fund redemptions (primarily as investors moved into equities or
withdrew their assets to meet tax obligations) and the upward migration of
interest rates. These factors contributed to the Fund's price depreciation
during the year.

When all was said and done, the Fund's duration did decline sufficiently to keep
total return on the positive side while providing a good income stream.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's average credit quality remained high during the fiscal year, with 89%
of the Fund invested in securities rated "AA" or better on June 30, 2000,
slightly higher than 86% on June 30, 1999.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's string of tightening moves over the past year finally
appears to be having the desired impact of slowing the economy. But, the current
expansion has displayed a remarkable level of resiliency. The chance of the
economy heating up again, coupled with the recent pick-up in the pace of
inflation, suggests that the Federal Reserve's job may not be over yet. This
translates into a market that may remain volatile and experience considerable
swings in sentiment over the near term. Our strategy in this environment will
continue to involve keeping a higher level of cash and controlling duration via
outright sales and swaps.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The above-quoted performance data includes the performance of the Pegasus
Michigan Municipal Bond Fund for the period prior to the acquisition by the One
Group Michigan Municipal Bond Fund on March 22, 1999.

The performance of the Michigan Municipal Bond Fund is measured against the
Lehman Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of
investment grade municipal bonds with maturities close to seven years. Investors
are unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lehman Brothers Michigan Municipal Bond Index is an unmanaged index
generally representative of the Michigan Municipal bond market.

The Lipper Michigan Municipal Debt Fund Index is comprised of funds that limit
their assets to those securities that are exempt from taxation in a specified
state (double tax-exempt) or city (triple tax-exempt).

The Lehman Brothers Michigan Municipal Bond Index consists of the average
monthly returns of the Lehman Brothers 7-Year Municipal Bond Index for periods
prior to April 1993. Thereafter, the data is from the Lehman Brothers Michigan
Municipal Bond Index, which corresponds with the initiation of the Lehman
Brothers Michigan Municipal Bond Index on April 1, 1993.

Portfolio Performance Review
--------------------------------------------------------------------------------
ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group Ohio Municipal Bond Fund I share
class posted a total return of 2.20%. (For information on other share classes
and performance comparisons to indexes, please see page 26.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
As expected, the municipal market took its cue from the Treasury market, and
ultimately the Federal Reserve. As such, the market came under price pressure
for most of the fiscal year, as interest rates generally moved upward. The
negative impact of the Federal Reserve's interest rate hikes was more than
enough to offset a number of positive factors that surfaced during the year. In
1998 the market experienced the second-highest year on record for new issuance.
But since then, the volume of new issuance has declined steadily to its current
pace that is 40% below that of 1998. In addition, the strong economy has helped
foster improvements in municipal credit ratings, with ratings upgrades outpacing
downgrades by a seven-to-one margin.

Nevertheless, these positive factors were not enough to prevent the municipal
market from underperforming the Treasury market. Declining supply, due to the
government surplus and the U.S. Treasury's buyback program of long-term debt,
and the occasional "flight to quality" caused Treasuries to outperform municipal
securities as well as agency and corporate bonds. We believe this pattern is not
likely to change any time soon, as the expected future surpluses should mean
more pay-down of debt.

HOW DID OHIO'S ECONOMY FARE?
The Ohio economy remained strong during the fiscal year, with revenues and
expenditures having positive influences on the state's budget. General revenue
fund balances were high enough not only to keep the budget stabilization fund at
its targeted level (5% of the general revenue fund), but also to fund various
reserves for such areas as school building and technology. This performance was
the result of the state's strong industrial base as well as its growing service
and trade sectors. This growth helped keep the state's unemployment rate down
near the 4% national average.

Looking forward, the sizeable "rainy day fund" coupled with the past and
continuing efforts to diversify the state's economic base away from
manufacturing into the service and trade sectors should help position the state
to better ride out future cyclical fluctuations. The major challenge over the
near-term remains the development of a new school funding structure. Reserves
are presently being set aside, however, the final structure has not been
determined. The final cost, nevertheless, is presently projected to be
manageable without the need for major draconian measures.

HOW DID MARKET EVENTS INFLUENCE PERFORMANCE?
The general increase in interest rates caused the Fund's share price to decline
over the 12-month period. The major contributor to performance was the Fund's
relatively high level of income, which offset the price depreciation and kept
the Fund's total return positive.

In response to the jump in tax-free interest rates over the fiscal year, the
Fund's 30 day SEC yield on I shares increased from 4.35% on June 30, 1999, to
4.83% on June 30, 2000. (For investors in the 39.6% federal income tax bracket
and the 7.5% Ohio state bracket, the 4.83% tax-exempt yield translates into an
8.65% taxable-equivalent yield.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
With our universe of securities limited to the state of Ohio, we consider
municipal bonds in all market
sectors. Our primary investment strategy continues to
involve purchasing high-quality, full-coupon, intermediate-maturity bonds with
good call structures. (Call refers to a bond issuer's right to repay, or "call,"
the bond prior to its maturity date.) This strategy is designed to provide a
good income stream while offering price protection when interest rates rise.

This past fiscal year demonstrated that trying to generate a high, steady stream
of income and maintain a stable net asset value are not always complimentary
goals. We initiated sales and swaps to raise cash and shorten the Fund's
duration as interest rates increased. (Duration is a measure of a fund's
sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) Nevertheless, these efforts
were largely offset by 24

Fund redemptions (primarily as investors moved into equities or withdrew their
assets to meet tax obligations) and the upward migration of interest rates.
These factors kept the Fund's duration at a higher-than-desired level, putting
downward pressure on returns. Stepping up the pace of our security sales would
have lowered duration more, but it also would have brought about a more volatile
income stream for shareholders. With interest rates settling into a trading
range over the last few months of the fiscal year, we determined that a slow
ratcheting-down of duration would be preferable to a large, one-time move based
on the potential impact on income.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's average credit quality remained high during the fiscal year, with 67%
of the Fund invested in securities rated "AAA."

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's string of tightening moves over the past year finally
appears to be having the desired impact of slowing the economy. But, the current
expansion has displayed a remarkable level of resiliency. The chance of the
economy heating up again, coupled with the recent pick-up in the pace of
inflation, suggests that the Federal Reserve's job may not be over yet. This
translates into a market that may remain volatile and experience considerable
swings in sentiment over the near term. Our strategy in this environment will
continue to involve keeping a higher level of cash and controlling duration via
outright sales and swaps.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the

The performance of the Ohio Municipal Bond Fund is measured against the Lehman
Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of investment
grade municipal bonds with maturities close to seven years. Investors are unable
to purchase the index directly, although they can invest in the underlying
securities. The performance of the index does not reflect the deduction of
expenses associated with a mutual fund, such as investment management fees. By
contrast, the performance of the Fund reflects the deduction of these services
as well as the deduction of sales charges on Class A shares and applicable
contingent deferred sales charges on Class B shares.

The Lipper Intermediate Municipal Fund Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

Portfolio Performance Review

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

HOW DID THE FUND PERFORM?
For the year ended June 30, 2000, One Group West Virginia Municipal Bond Fund I
share class posted a total return of 2.76%. (For information on other share
classes and performance comparisons to indexes, please see page 29.)

WHAT WERE THE MAJOR FACTORS AT WORK IN THE MARKET?
As expected, the municipal market took its cue from the Treasury market, and
ultimately the Federal Reserve. As such, the market came under price pressure
for most of the fiscal year, as interest rates generally moved upward. The
negative impact of the Federal Reserve's interest rate hikes was more than
enough to offset a number of positive factors that surfaced during the year. In
1998 the market experienced the second-highest year on record for new issuance.
But since then, the volume of new issuance has declined steadily to its current
pace that is 40% below that of 1998. In addition, the strong economy has helped
foster improvements in municipal credit ratings, with ratings upgrades outpacing
downgrades by a seven-to-one margin.

Nevertheless, these positive factors were not enough to prevent the municipal
market from underperforming the Treasury market. Declining supply, due to the
government surplus and the U.S. Treasury's buyback program of long-term debt,
and the occasional "flight to quality" caused Treasuries to outperform municipal
securities as well as agency and corporate bonds. We believe this pattern is not
likely to change any time soon, as the expected future surpluses should mean
more pay-down of debt.

HOW DID THE STATE'S ECONOMY FARE?
West Virginia continues to make progress in moving from one of the nation's
weakest states a decade ago to one on solid fiscal ground. The major factors
leading to this transformation have been a strong national economy, state
budgetary reforms and a diversification of the state's economic base from the
cyclical mining and metals industries to the more stable service sector.

The state posted another operating surplus this past fiscal year while building
its "rainy day" fund to 6% of general fund disbursements. This performance was
accompanied by another year of slow but steady growth in employment. While still
high by national standards, the level of unemployment continued to fall, and it
currently is at its lowest level in 20 years.

The near-term outlook points to continued modest growth, as long as the national
economy keeps moving forward. The state's low cost base plus its central
location are positives. But, West Virginia still possesses a number of
weaknesses that stifle its progress, namely a slow-growing and aging population,
low educational achievements and a lack of broad economic diversity. The state
is addressing these issues, but resolving them obviously will take time.

HOW DID MARKET EVENTS INFLUENCE PERFORMANCE?
The general increase in interest rates caused the Fund's share price to decline
over the 12-month period. The major contributor to performance was the Fund's
relatively high level of income, which offset the price depreciation and kept
the Fund's total return positive.

In response to the jump in tax-free interest rates over the fiscal year, the
Fund's 30 day SEC yield on I shares increased from 4.29% on June 30, 1999, to
4.83% on June 30, 2000. (For investors in the 39.6% federal income tax bracket
and the 6.5% West Virginia state bracket, the 4.83% tax-exempt yield translates
into an 8.55% taxable-equivalent yield.)

WHAT WERE YOUR PRIMARY STRATEGIES AND TACTICS?
Because our investment selections are limited to the state of West Virginia, we
consider bonds in all market sectors. Our primary investment strategy continues
to involve purchasing high-quality, full-coupon, intermediate-maturity bonds
with good call structures. (Call refers to a bond issuer's right to repay, or
"call," the bond prior to its maturity date.) This strategy is designed to
provide a good income stream while offering price protection when interest rates
rise.

This past fiscal year demonstrated that trying to generate a high, steady stream
of income while maintaining a stable net asset value can be challenging dual
goals. As interest rates increased, we initiated sales and swaps to raise cash
and shorten the Fund's duration, which moved from 6.4 years on June 30, 1999, to
5.8 years on June 30, 2000. (Duration is a measure of a

fund's sensitivity to interest rate changes. A longer duration indicates greater
sensitivity; a shorter duration indicates less.) But these efforts were largely
offset by Fund redemptions (primarily as investors moved into equities or
withdrew their assets to meet tax obligations) and the upward migration of
interest rates, which pushed duration to more than 6 years during the third and
fourth quarters of 1999. When all was said and done, the Fund's duration did
decline sufficiently to keep total return relatively attractive and provide a
good income stream.

HOW WAS THE FUND STRUCTURED IN TERMS OF QUALITY?*
The Fund's average credit quality remained high during the fiscal year, with 82%
of the Fund invested in securities rated "AA" or better on June 30, 2000,
slightly lower than 83% on June 30, 1999.

WHAT IS YOUR OUTLOOK FOR THE FUND?
The Federal Reserve's string of tightening moves over the past year finally
appears to be having the desired impact of slowing the economy. But, the current
expansion has displayed a remarkable level of resiliency. The chance of the
economy heating up again, coupled with the recent pick-up in the pace of
inflation, suggests that the Federal Reserve's job may not be over yet. This
translates into a market that may remain volatile and experience considerable
swings in sentiment over the near term. Our strategy in this environment will
continue to involve keeping a higher level of cash and controlling duration via
outright sales and swaps.

The performance data quoted represents past performance and is not an indication
of future results. Investment return and NAV will fluctuate so that an
investor's shares, when redeemed, may be worth more or less than the original
cost. The total return set forth may reflect the waiver of a portion of the
fund's fees for certain periods since the inception date, without the waiver,
total return would have been lower.

The fund's income may be subject to the federal alternative minimum tax.

The above-quoted performance data includes the performance of a collective trust
fund for the period prior to the commencement of operations of the mutual fund
on January 20, 1997, adjusted to reflect the expenses associated with the Fund.
The collective trust fund was not registered under the Investment Company Act of
1940 ("1940 Act") and, therefore, was not subject to certain investment
restrictions, limitations and diversification requirements imposed by the 1940
Act and the Internal Revenue Code. If the collective trust fund had been
registered under the 1940 Act, its performance may have been adversely affected.

The performance of the West Virginia Municipal Bond Fund is measured against the
Lehman Brothers 7 Year Municipal Bond Index, an unmanaged index comprised of
investment grade municipal bonds with maturities close to seven years. Investors
are unable to purchase the index directly, although they can invest in the
underlying securities. The performance of the index does not reflect the
deduction of expenses associated with a mutual fund, such as investment
management fees. By contrast, the performance of the Fund reflects the deduction
of these services as well as the deduction of sales charges on Class A shares
and applicable contingent deferred sales charges on Class B shares.

The Lipper Intermediate Municipal Fund Index consists of the equally weighted
average monthly return of the largest funds within the universe of all funds in
the category.

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS                                      JUNE 30, 2000

1. ORGANIZATION:

   The One Group Mutual Funds (the "Trust") is registered under the Investment
   Company Act of 1940, as amended (the "1940 Act"), as an open-end investment
   company established as a Massachusetts business trust. The accompanying
   financial statements and financial highlights are those of the Short-Term
   Municipal Bond Fund, Intermediate Tax-Free Bond Fund, Tax-Free Bond Fund,
   Municipal Income Fund, Arizona Municipal Bond Fund, Kentucky Municipal Bond
   Fund, Louisiana Municipal Bond Fund, Michigan Municipal Bond Fund, Ohio
   Municipal Bond Fund and West Virginia Municipal Bond Fund, (individually a
   "Fund", collectively the "Funds") only. Each Fund is a non-diversified mutual
   fund, except for Short-Term Municipal Bond Fund, Intermediate Tax-Free Bond
   Fund, Tax-Free Bond Fund and Municipal Income Fund, which are diversified.

2. SIGNIFICANT ACCOUNTING POLICIES:

   The following is a summary of significant accounting policies followed by the
   Trust in the preparation of its financial statements. The policies are in
   conformity with generally accepted accounting principles. The preparation of
   financial statements requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities at the date of the
   financial statements and the reported amounts of income and expenses for the
   period. Actual results could differ from those estimates.

     SECURITY VALUATION

     Debt securities (other than short-term investments maturing in 60 days or
     less), including municipal securities, are valued on the basis of
     valuations provided by dealers or by an independent pricing service
     approved by the Board of Trustees. Short-term investments maturing in 60
     days or less are valued at amortized cost, which approximates market value.
     Futures contracts are valued at the settlement price established each day
     by the board of trade or an exchange on which they are traded. Options
     traded on an exchange are valued using the last sale price or, in the
     absence of a sale, the mean of the latest bid and ask prices. Options
     traded over-the-counter are valued using dealer-supplied valuations.
     Investments for which there are no such quotations or valuations are valued
     at fair value as determined in good faith by the Pricing Committee, which
     is comprised of members from One Group Administrative Services ("OGA"), an
     affiliate of Banc One Investment Advisors Corporation (the "Advisor") and
     the One Group Services Company (the "Administrator"), under the direction
     of the Board of Trustees.

     REPURCHASE AGREEMENTS

     The Funds may invest in repurchase agreements with institutions that are
     deemed by the Advisor to be of good standing and creditworthy under
     guidelines established by the Board of Trustees. Each repurchase agreement
     is recorded at cost. The Fund requires that the securities purchased in a
     repurchase agreement transaction be transferred to the custodian in a
     manner sufficient to enable the Fund to obtain those securities in the
     event of a counterparty default. The seller, under the repurchase
     agreement, is required to maintain the value of the securities held at not
     less than the repurchase price, including accrued interest. Repurchase
     agreements are considered to be loans by a fund under the 1940 Act.

     FUTURES CONTRACTS

     The Funds may enter into futures contracts for the delayed delivery of
     securities at a fixed price at some future date or for the change in the
     value of a specified financial index over a predetermined time period. Cash
     or securities are deposited with brokers in order to maintain a position.
     Subsequent payments made or received by the Fund based on the daily change
     in the market value of the position are recorded as unrealized appreciation
     or depreciation until the contract is closed out, at which time the
     appreciation or depreciation is realized.

NOTES TO FINANCIAL STATEMENTS, CONTINUED                           JUNE 30, 2000

     FINANCIAL INSTRUMENTS

     Investing in financial instruments such as written options, futures,
     structured notes and indexed securities involves risks in excess of the
     amounts reflected in the Statements of Assets and Liabilities. The face or
     contract amounts reflect the extent of the involvement the Funds have in
     the particular class of instrument.

     Risks associated with these instruments include an imperfect correlation
     between the movements in the price of the instruments and the price of the
     underlying securities and interest rates, an illiquid secondary market for
     the instruments or inability of counterparties to perform under the terms
     of the contract. The Funds enter into these contracts primarily as a means
     to hedge against adverse fluctuation in securities.

     SECURITY TRANSACTIONS AND RELATED INCOME

     Security transactions are accounted for on a trade date basis. Net realized
     gains or losses from sales of securities are determined on the specific
     identification cost method. Net investment income and expenses are
     recognized on the accrual basis. Dividends are recorded on the ex-dividend
     date. Interest income includes premium amortization and discount accretion
     for both financial reporting and tax purposes. Amortization and accretion
     are calculated using the effective interest method.

     EXPENSES

     Expenses directly attributable to a Fund are charged directly to that Fund,
     while the expenses which are attributable to more than one Fund of the
     Trust, are allocated among the respective Funds. Each class of shares bears
     its pro-rata portion of expenses attributable to its series, except that
     each class separately bears expenses related specifically to that class,
     such as distribution fees.

     DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

     Dividends from net investment income are declared daily and paid monthly
     for the Funds. Net realized capital gains, if any, are distributed at least
     annually. Dividends are declared separately for each class. No class has
     preferential dividend rights; differences in per share dividend rates are
     due to differences in separate class expenses.

     Distributions from net investment income and from net capital gains are
     determined in accordance with income tax regulations, which may differ from
     generally accepted accounting principles. These differences are primarily
     due to differing treatments for expiring capital loss carryforwards and
     deferrals of certain losses. Permanent book and tax basis differences have
     been reclassified among the components of net assets. Certain funds may
     utilize earnings and profits distributed to shareholders on redemption of
     shares as part of the dividends paid deduction for income tax purposes.

     FEDERAL INCOME TAXES

     Each Fund intends to continue to qualify as a regulated investment company
     by complying with the provisions available to certain investment companies
     as defined in applicable sections of the Internal Revenue Code, and to make
     distributions from net investment income and net realized capital gains
     sufficient to relieve it from all, or substantially all, federal income
     taxes.

     DEFERRED ORGANIZATION COSTS

     Prior to June 30, 1998, costs incurred by the Trust in connection with its
     organization, including the fees and expenses of registering and qualifying
     its shares for distribution were deferred and are being amortized using the
     straight-line method over a period of five years beginning with the
     commencement of each Fund's operations. All such costs, which are
     attributable to more than one Fund of the Trust, have been allocated among

     the respective Fund's pro-rata, based on the relative net assets of each
     Fund. In the event that any of the initial shares are redeemed during such
     period by any holder thereof, the related fund will be reimbursed by such
     holder for any unamortized organization costs in the proportion as the
     number of initial shares being redeemed bears to the number of initial
     shares outstanding at the time of redemption.

3. SHARES OF BENEFICIAL INTEREST:

   The Trust has an unlimited number of shares of beneficial interest, with no
   par value, which may, without shareholder approval, be divided into an
   unlimited number of series of such shares, and any series may be classified
   or reclassified into one or more classes. The Trust is registered to offer
   fifty-four series and six classes of shares: Class I, Class A, Class B, Class
   C, Class S and Service Class. Currently, the Trust consists of forty-nine
   active funds. The Funds are each authorized to issue Class I, Class A, Class
   B and Class C shares. Class A shares are subject to initial sales charges,
   imposed at the time of purchase, in accordance with the Funds' prospectus.
   Certain redemptions of Class B and Class C shares are subject to contingent
   deferred sales charges in accordance with the Funds' prospectus. As of June
   30, 2000, there were no shareholders in Class C of the Funds except for the
   Municipal Income Fund. Shareholders are entitled to one vote for each full
   share held and vote in the aggregate and not by class or series, except as
   otherwise expressly required by law or when the Board of Trustees has
   determined that the matter to be voted on affects only the interest of
   shareholders of a particular class or series. See Schedules of Capital Stock
   Activity.

4. INVESTMENT ADVISORY, ADMINISTRATION, AND DISTRIBUTION AGREEMENTS:

   The Trust and the Advisor are parties to an investment advisory agreement
   under which the Advisor is entitled to receive an annual fee, computed daily
   and paid monthly, equal to the following percentages of the Funds' average
   daily net assets: 0.60% of the Short-Term Municipal Bond Fund, the
   Intermediate Tax-Free Bond Fund, the Louisiana Municipal Bond Fund and the
   Ohio Municipal Bond Fund; 0.45% of the Tax-Free Bond Fund, the Municipal
   Income Fund, the Arizona Municipal Bond Fund, the Kentucky Municipal Bond
   Fund, the Michigan Municipal Bond Fund and the West Virginia Municipal Bond
   Fund.

   The Trust and the Administrator, a wholly-owned subsidiary of The BISYS
   Group, Inc., are parties to an administration agreement under which the
   Administrator provides services for a fee that is computed daily and paid
   monthly, at an annual rate of 0.20% on the first $1.5 billion of Trust net
   assets (excluding the Investor Conservative Growth Fund, the Investor
   Balanced Fund, the Investor Growth & Income Fund, and the Investor Growth
   Fund, (the "Investor Funds") and the Institutional Prime Money Market Fund,
   the Treasury Only Money Market Fund, and the Government Money Market Fund,
   (the "Institutional Money Market Funds")); 0.18% on the next $0.5 billion of
   Trust net assets (excluding the Investor Funds and the Institutional Money
   Market Funds); and 0.16% of Trust net assets (excluding the Investor Funds
   and the Institutional Money Market Funds) over $2 billion. OGA also serves as
   Sub-Administrator to each fund of the Trust, pursuant to an agreement between
   the Administrator and OGA. Pursuant to this agreement, OGA performs many of
   the Administrator's duties, for which OGA receives a fee paid by the
   Administrator.

   The Trust and The One Group Services Company (the "Distributor") are parties
   to a distribution agreement under which shares of the Funds are sold on a
   continuous basis. Class A, Class B and Class C shares are subject to
   distribution and shareholder services plans (the "Plans") pursuant to Rule
   12b-1 under the 1940 Act. As provided in the Plans, the Trust will pay the
   Distributor a fee of 0.35% of the average daily net assets of Class A shares
   of each of the Funds and 1.00% of the average daily net assets of the Class B
   and Class C shares of each of the Funds. Currently, the Distributor has
   voluntarily agreed to limit payments under the Plans to 0.25%, 0.90% and
   0.90% of average daily net assets of the Class A, Class B and Class C shares,
   respectively, of each Fund. Up to 0.25% of the fees payable under the Plans
   may be used as compensation for shareholder services by the Distributor
   and/or financial institutions and intermediaries. Fees paid under the Plans
   may be applied by the Distributor toward (i) compensation for its services in
   connection with distribution assistance or provision of shareholder

   services; or (ii) payments to financial institutions and intermediaries such
   as banks (including affiliates of the Advisor), brokers, dealers and other
   institutions, including the Distributor's affiliates and subsidiaries as
   compensation for services or reimbursement of expenses incurred in connection
   with distribution assistance or provision of shareholder services. Class I
   shares of each Fund are offered without distribution fees. For the year ended
   June 30, 2000, the Distributor received $494,155 from commissions earned on
   sales of Class A shares and redemptions of Class B and Class C shares, of
   which the Distributor reallowed $105,899 to affiliated broker/dealers of the
   Funds.

   Certain officers of the Trust are affiliated with the Administrator. Such
   officers receive no compensation from the Funds for serving in their
   respective roles.

   The Advisor, the Administrator and the Distributor voluntarily agreed to
   waive a portion of their fees. For the year ended June 30, 2000, fees in the
   following amounts were waived (amounts in thousands):

6. LINE OF CREDIT:

   The Trust and State Street Bank and Trust Company ("State Street") and a
   group of banks (collectively, the "Banks") entered into a financing agreement
   dated October 19, 1999. Under this agreement, the Banks provide an unsecured
   committed credit facility in the aggregate amount of $500 million. The credit
   facility is allocated, under the terms of the financing agreement, among the
   Banks. Advances under the agreement are taken primarily for temporary or
   emergency purposes, including the meeting of redemption requests that
   otherwise

   might require the untimely disposition of securities, and are subject to each
   Fund's borrowing restrictions. Interest on borrowings is payable at the
   Federal Funds Rate plus 0.50% on an annualized basis. Interest on borrowings
   during the period from and including December 15, 1999 to January 17, 2000,
   was payable at 0.50% plus the higher of the Fed Funds Effective Rate plus
   0.50% or the Fed Funds Target Rate plus 1.50%. A commitment fee of 0.10% per
   annum will be incurred on the unused portion of the committed facility, which
   is allocated to all funds of the Trust.

   During the year ended June 30, 2000, there were no borrowings by the Funds
   under the Agreement.

7. DEFERRED COMPENSATION PLAN:

   Independent Trustees of the Funds may participate in a Deferred Compensation
   Plan in which they may defer any or all compensation related to performance
   of their duties as a Trustee. All deferred compensation is paid by the Funds
   and invested into various One Group funds elected by each Trustee. The Plan
   is fully funded and therefore, the Funds bear no additional trustee expense
   over and above the normal cash compensation.

8. CONCENTRATION OF CREDIT RISK:

   The Arizona, Kentucky, Louisiana, Michigan, Ohio and West Virginia Municipal
   Bond Funds invest primarily in debt obligations issued by the respective
   States and their political subdivisions, agencies and public authorities to
   obtain funds for various public purposes. The Funds are more susceptible to
   economic and political factors adversely affecting issuers of the State's
   specific municipal securities than are municipal bond funds that are not
   concentrated in these issuers to the same extent.

9. CONVERSION OF COMMON TRUST FUNDS:

   The net assets of certain common trust funds managed by First Chicago NBD
   Investment Management Company (an affiliate of the Advisor) were exchanged in
   a tax-free conversion for Class I shares of the corresponding Funds. The
   transactions were accounted for by a method followed for tax purposes in a
   tax-free business combination. The following is a summary of dates, shares
   issued, net assets converted, net asset value per share issued and unrealized
   appreciation of assets acquired as of the conversion date (amounts in
   thousands except per share amounts):

ONE GROUP MUTUAL FUNDS                                             JUNE 30, 2000

To the Board of Trustees and Shareholders of
   One Group Mutual Funds:

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of portfolio investments, and the related statements of operations
and of changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the Short-Term Municipal Bond Fund,
the Intermediate Tax-Free Bond Fund, the Tax-Free Bond Fund, the Municipal
Income Fund, the Arizona Municipal Bond Fund, the Kentucky Municipal Bond Fund,
the Louisiana Municipal Bond Fund, the Michigan Municipal Bond Fund, the Ohio
Municipal Bond Fund and the West Virginia Municipal Bond Fund (ten series of One
Group Mutual Funds, hereafter referred to as the "Funds") at June 30, 2000, and
the results of each of their operations for the year then ended and the changes
in each of their net assets and the financial highlights for each of the periods
presented (other than those statements of operations, statements of changes in
net assets and financial highlights that have been audited by other independent
accountants), in conformity with accounting principles generally accepted in the
United States. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Funds'
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with auditing standards generally accepted in the
United States, which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at June 30, 2000 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above. The financial statements of the Short-Term
Municipal Bond Fund, the Tax-Free Bond Fund and the Michigan Municipal Bond Fund
for all periods ended on or before December 31, 1998 were audited by other
independent accountants whose report dated February 12, 1999, expressed an
unqualified opinion on those statements and financial highlights.
